  • Patent number: 5008031
    Abstract: A liquid detergent based on nonionic and anionic surfactants, and optionally particulate builder materials, contains a non-surfactant component which increases the wash efficiency, comprising the combination of low-polarity and mid- to high-polarity organic liquids. The low-polarity liquids are hydrocarbons, while the mid- to high-polarity liquids are esters, ethers, ketones or alcohols. The detergents have a satisfactory viscosity behavior, good miscibility with water and good wash efficiency.

  • Patent number: 4963158
    Abstract: Soiled textile articles are washed by the addition of a determined amount of a detergent concentrate containing surfactants to the textile articles to be cleaned while the textiles are dry or only damp. The aqueous washing liquor is formed by the gradual addition of water to the textile articles while they are rotated. At room temperature, the detergent concentrate is to a substantial extent a paste-to dough-like substance, stable in form, and is applied to the textile articles in such an amount that the major portion of the surfactants together with further detergent constituents, if desired, are applied to the textiles or on an article of textile provided with markings for the correct detergent dose, as a dosing aid.

  • Patent number: 4243391
    Abstract: The invention relates to a process for bleaching washed textiles in the tumbler of a mechanical laundry drier with an aqueous solution of hydrogen peroxide in an amount such that the residual moisture adhering to the textile material before drying contains 0.05 to 1 gm/liter of hydrogen peroxide, the drying being conducted so that the moist textile material assumes a temperature of at least 50.degree. C., preferably 55.degree. C. to 80.degree. C., for a period of at least 10 to 60 minutes. An addition of quaternary ammonium salts improves the bleach result and the softness of the textile material. An addition of a powdered bleaching activator of the N-acyl type also improves the bleach results.
